Economic techniques to estimate the demand for sustainable products: a case study for fair trade and organic coffee in the United Kingdom

Abstract: El presente articulo se basa en la utilizacion del metodo hedonico para la estimacion de la cantidad que se paga por la caracteristica de «Organico/Comercio Justo» del cafe en el mercado britanico. La informacion obtenida se combina despues con el modelo Sistema de Demanda Basado en Cantidades (QBDS) – desarrollado por los autores— y el Sistema de Demanda Casi Ideal (AIDS) (Deaton and Muellbauer, 1980) para determinar por completo la funcion de demanda de los diferentes tipos de cafe. El modelo QBDS es mas sencillo en su utilizacion y necesita de menos datos que el modelo AIDS.

Adapting the shipping sector to stricter emissions regulations: Fuel switching or installing a scrubber?

Abstract: This paper examines how the existing fleet in the shipping industry can be adapted to the new emission regulations through the two main techniques that currently exist: (a) the use of low-sulphur marine diesels; and (b) the installation of scrubbers. A method is presented here for drawing up an economic assessment of both these techniques under uncertainty. It enables the best option to be selected at any given time taking into account fuel prices (spot and futures), scrubber installation costs, the time that the vessel operates in an Emission Control Area (ECA) and the remaining useful lifetime of the vessel. The paper also considers the possibility of an unexpected change from a non-ECA navigation area to an ECA. The assessment is carried out in a manner consistent with marine diesel and crude oil spot and futures market quotes. Our results show the net present value of investing in the installation of scrubbers and investing in changing fuel types for different assumptions on how vessels are operated. We also analyse increases in fuel consumption and CO2 emissions as a consequence of using scrubbers and how they affects the financial analysis if such incremental emissions must be paid under a CO2 pricing mechanism.

The Role of Regional Governments in Climate Change Policy

Abstract: Climate change is one of the greatest challenges facing us, and it requires urgent policy action. Although climate change policies are mainly being discussed at international level by means of the United Nations Conventions and the Kyoto Protocol, the bulk of the impact will be felt at regional and local level. Regional and local governments are thus important actors. Moreover, regional governments in many parts of the world hold a wide range of the competences to implement policy actions for both adaptation and mitigation. This paper illustrates the important role of regions in climate policies and considers many of the policy instruments being designed and implemented. The paper describes 23 leading regions in climate policy. Finally, the case of Basque climate policy is described as an example of an industrial region in Europe where the degree of decentralization is significant.

Climate Change 2007: Impacts, Adaptation and Vulnerability.

Abstract: Impatti, adattamento e vulnerabilita Le cause e le responsabilita dei cambiamenti climatici sono state trattate sul numero di ottobre della rivista Cda. Approfondiamo l’argomento presentando il documento: “Cambiamenti climatici 2007: impatti, adattamento e vulnerabilita” votato ad aprile 2007 dal secondo gruppo di lavoro del Comitato Intergovernativo sui Cambiamenti Climatici (Intergovernmental Panel on Climate Change). Si tratta del secondo di tre documenti che compongono il quarto rapporto sui cambiamenti climatici.

On making causal claims : A review and recommendations

Abstract: Social scientists often estimate models from correlational data, where the independent variable has not been exogenously manipulated; they also make implicit or explicit causal claims based on these models. When can these claims be made? We answer this question by first discussing design and estimation conditions under which model estimates can be interpreted, using the randomized experiment as the gold standard. We show how endogeneity – which includes omitted variables, omitted selection, simultaneity, common-method variance, and measurement error – renders estimates causally uninterpretable. Second, we present methods that allow researchers to test causal claims in situations where randomization is not possible or when causal interpretation could be confounded; these methods include fixed-effects panel, sample selection, instrumental variable, regression discontinuity, and difference-in-differences models. Third, we take stock of the methodological rigor with which causal claims are being made in a social sciences discipline by reviewing a representative sample of 110 articles on leadership published in the previous 10 years in top-tier journals. Our key finding is that researchers fail to address at least 66% and up to 90% of design and estimation conditions that make causal claims invalid. We conclude by offering 10 suggestions on how to improve non-experimental research.

Risk-Aversion and Willingness to Pay For Energy Saving Measures in Residential Buildings

Abstract: This paper uses a choice experiment to evaluate the consumers' willingness to pay for energy-saving measures in Switzerland's residential buildings. These measures include air renewal (ventilation) systems and insulation of windows and facades. Two groups of respondents consisting respectively of 163 apartment tenants and 142 house owners were asked to choose between their housing status quo and each one of the several hypothetical situations with different attributes and prices. The estimation method is based on a fixed-effects logit model. The results suggest that the benefits of the energy-saving attributes are significantly valued by the consumers. These benefits include both individual energy savings and environmental benefits as well as comfort benefits namely, thermal comfort, air quality and noise protection.
